Description

The invention is based on the application conditions defined in the preamble of claim 1. The invention proposed here should help to realize the industrial and manual implementation of operations such as welding, soldering and bolting sheet metal parts under the specific vertical vertical thin sheets effectively and in good quality.

Operations of this kind are on the clamping table surfaces of existing work, assembly and welding tables but also on clamping pallets or device base plates, as far as a clamping device is to be used to hold perform. It is desirable to design the working equipment to be used flexibly, space-saving and positioned free of hydraulic and electrical lines on a clamping table surface. Under the aspect of a vertical arrangement of sheet metal parts to be joined as well as the materials used, including non-ferromagnetic and plastic materials, high solution requirements are placed on a deflection-free alignment and holding these sheet metal parts as well as a sufficiently large and secure holding force going out of the ordinary professional knowledge.

Das Fügen von dünnen Blechen ist durchführbar, nachdem eine An- und Auflagepositionierung mittels Hilfselementen erfolgte.

On the worktable surfaces of worktables these can be positioned and fixed in equidistant bores and T-slots by the operator of this joining workstation. The joining of thin sheets is feasible after an arrival and support positioning was done by means of auxiliary elements. The disadvantage of using these embodiments that in the vertical position to be fixed sheet metal parts held only on the front side and not in their middle positions and thus unwanted deflections can not be excluded.

• • DE 4315 441 C2 includes a clamping and abutment body with base plate for measurement purposes, but which can also be used for holding in vertical position zuhaltenenden thin sheets. The magnetic field carriers are cylindrical small permanent magnets, which, despite their use in a larger, distributed over the contact surfaces number, in the sum only a small, not sufficient for a secure sheet holder holding power. Permanent magnets, integrated on all sides into separate magnetic holding bodies, are in
